MDO-2000E

The limitation in the general FFT in the DSO• The operational logic of FFT function is restricted by the sample rate setting of

source channels and FFT calculation points.

• A correct spectrum cannot be observed if the horizontal scale can’t be appropriately setup.

• Insufficient calculation efficiency of CPU platform will also restrain oscilloscopes’ capabilities in providing FFT measurements.

• Conventional DSO’s FFT always calculates the

entire signal bandwidth up to half the sampling

rate (Fs).. However, the insufficient calculation

capability can’t conduct multi-point FFT

calculation. (above figure)

• MDO-2000E analyzes signal spectrum of interest.

Compared with oscilloscope’ FFT, MDO-2000E

series allows engineers to effectively conduct

signal measurements on frequency domain.

(below figure).

The input signal is FSK

500mVpp sine wave

• fmax: 10.2MHz,

• fmin: 10.0MHz,

• bit rate: 10.0kHz.

Users can directly input Center and Span Frequency by an intuitive and swift setting.

fmax and fmin can be clearly identified from the screen display by MDO-2000E.

• The boundary started from DC (low frequency signal) and the maximum frequency

on the right is half of the sample rate.

• The users can’t set Span ,the Span setting for spectrum can only be switched by

fixed 1-2-5 multiplying factors

• Only conduct Zoom In/Out calculation on the original FFT spectrum

• The important fmax and fmin of spectrum can’t be identified.

• To enhance original FFT’s UI. To provide frequency domain display as the spectrum analyzer.

• Frequency setup allow to set Center/Span or Start/Stop

• The unit of amplitude display is dB .

• Allow to use maker to display the test frequency

Spectrum analyzer introduction

11

The user is allow to set Start Frequency, Stop Frequency, Center Frequency, and Span to intuitively and

rapidly identify the desired frequency range

Frequency Setup

12

In order to allow users to experience genuine Spectrum Analyzer, MDO-2000E also includes Spectrum

Trace Type settings (Normal, Max-hold, Min-hold, and Average). Users can freely simultaneously

select various Spectrum Traces.

13

The advantages of SA function in MDO-2000E

1. Compare to normal Spectrum Analyzer ,MDO-2000E is

allow to test the frequency below 9kHz and test DC+AC

signal. (The applications of less than 9kHz are main in vibration and audio).

2. The test speed is faster than normal Spectrum

Analyzer.

3.Users can directly input Center and Span

Frequency by an intuitive and swift setting.

Frequency components can be clearly identified.

MDO-2000EX equips with DMM and power supply.

• Each DMM setting level is calibrated by precision calibration procedures.

• The DVM of the general oscilloscopes is only the functional extension of Auto

measurement, which has a basic measurement error of approximately DC Gain

Accuracy 3% and its accuracy cannot compete with the actual DMM.

• The highly accurate DMM can strengthen DSO’s capabilities of voltage and current

measurement accuracy.
